I have attached the script I used to provide a XML via a HTTP request. It is 
basically a frontend to the BB hobbitdxboard command, it will work with any 
of it's possible fields. It will also cache the response for a given query 
for 30 seconds (configureable). I did not want my Hobbit server spammed with 
the same XML queries. Though this does mean, whatever directory used to store 
the tmp cache files has alot of files, since there is really no automated 
cleanup of the files.

Hope this is somewhat helpful.
